[jira] [Created] (ZOOKEEPER-3870) Avoid out of order response and txns created with ReadOnlyZooKeeperServer

Fangmin Lv created ZOOKEEPER-3870:
-------------------------------------

             Summary: Avoid out of order response and txns created with ReadOnlyZooKeeperServer
                 Key: ZOOKEEPER-3870
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3870
             Project: ZooKeeper
          Issue Type: Bug
          Components: server
    Affects Versions: 3.6.1
            Reporter: Fangmin Lv
            Assignee: Fangmin Lv


The current ReadOnlyZooKeeperServer was implemented with PrepRequestProcessor, which will prepare txn even in read only mode.

Also, it will fail the write request in ReadOnlyRequestProcessor, which will cause out of order response issue. 

This Jira is going to fix this by replacing the PrepRequestProcessor with CommitProcessor, same as the other learner set up.
